Principles of ancient bronze locks
We can clearly see some doorways from various ancient bronze locks in the picture. In fact, the principle of this lock is obvious. Firstly, the principle of the lock is introduced: generally, there will be three shrapnel under the lock core. The right side of this shrapnel is fixed on the right side of the beam under the lock core, and the corresponding left side extends outward. When we lock the lock, the lock core will be inserted along the left slot of the lock, and the corresponding elastic sheet will be pressed during the insertion. When the lock core is inserted, the corresponding shrapnel will naturally pop up. We know that when the spring piece is pressed down, the slot is just big enough to be inserted, so once the spring piece is opened, it will abut against the inner wall of the left lock, at this time, the copper lock will be locked, and the beam above the corresponding copper lock will be inserted into the right slot of the copper lock.
The principle of unlocking is also relatively simple. When we understand the principle of locking, the principle of unlocking is better understood. When unlocking, insert the key with the same groove at the top into the copper lock from the right, align the groove on the key with the groove of the lock core and continue to push forward, and the corresponding key will move forward along this groove. When the keyhole advances gradually, it will recompress the bounced shrapnel, so the lock core loses its resistance and is pushed out from the left. The depth of this keyway hole is just enough to ensure that the key can be pushed out of the lock core, but it cannot fall into the lock shell itself.
To sum up, there is a certain reason why copper locks can be used for a long time, that is, using copper as a material can prevent corrosion. The second is to design with simple physical principles, and there is no complicated structure to ensure that the function will not fail. Thirdly, the key with simple structure will not damage the lock.
The price of ancient bronze locks
In the market, these ancient bronze locks seem to have become a kind of handicraft, and the price of this handicraft is not the general use price. But after all, there are many contrasts in this kind of bronze phase lock, so the price is relatively low. Generally, in some antique markets, the price of antique locks is tens of yuan. But there are also some ancient bronze locks with a long history, and the price has reached thousands or even tens of thousands of yuan.
Copper lock identification
How to tell the authenticity of a bronze lock?
The metal lock was invented in the Han Dynasty to lock the reed. Ancient bronze locks have high appreciation value, and there are few imitations in the market, such as tricolor bronze locks in Ming Dynasty, crane locks, coded locks, hidden locks, four locks, inverted locks, figures, animals and figures locks in Qing Dynasty, which are all worth collecting.
The types of ancient locks are divided into two categories: reed structure locks and character cipher locks. Reed locks are divided into wide locks, Citigroup locks, torture locks and jewelry locks, mostly horizontal locks, which are used for doors, cabinets and boxes. Guangxu was prolific in Shaoxing, commonly known as "Shaosuo". Most of these locks are made of copper, with concave front and triangular and rectangular end faces. The wide locks before the Ming Dynasty were all long cylindrical end faces. The wide locks in the Ming and Qing Dynasties were triangular on the top and oblique on the bottom. In the Qing dynasty, it was mostly brass, and there were also Yunnan white copper and iron. The upper part of the end face is the same as that of the Ming and Qing Dynasties, and the lower part is square.
Some traditional locks are like a pair of mandarin ducks, which need two keys to open at the same time. Insert the key into the mechanism and knock the lock three times to open it. I have seen a bronze lock with five words on it. If you want to open the lock, you need to pair these words into five-character quatrains. Only when the poem is right will the lock be opened.
With some high-quality products in the auction market hitting sky-high prices, the prices of many ordinary copper locks are also rising, and collectors should always tighten the string of fakes. Bian Xiao reminded hardware lock collectors that there are several essentials to identify the authenticity of copper locks:
(1) Looking at copper, some copper locks are plated with copper or painted yellow;
(2) Looking at the pattern, the genuine product does not feel concave and convex, and the pattern "corroded" by chemical methods may be imitation;
(3) Look at the process of the lock to see if there are splicing marks at both ends, and open the lock to see if the reed inside is welded; Password lock should distinguish authenticity from lettering. When collecting copper locks, we should pay attention to whether the keys are original, and copper locks with original keys are more valuable for collection.
Copper locks have always occupied a very important position in the collection market. Unlike wooden locks and iron locks. Copper locks have many fans in the collection market, but how to choose a copper lock with collection value and appreciation space? The author thinks that modeling, ornamentation, sculpture and other factors are the focus of attention. The above is about ancient bronze locks, I hope it will help you!
